Whenever a change is made to the machine control pattern, also exchange the pattern card in the cab to match the new pattern. Check the machine control pattern for conformance to the pattern on the card in the cab. If the pattern does not match, change the card to match the machine control pattern before you operate the machine. Failure to do so could result in personal injury. |
The machine control pattern can be changed to the SAE system by changing the position of the two-way valve (if equipped). The machine control pattern can also be changed to the standard backhoe loader hydraulic system (BHL) by changing the valve position. Use the following procedure to change the position of the two-way valve.
The two-way valve is located inside the front left access door.

- Pull up on lever (a) and turn the lever to the SAE position or to the BHL position.
Note: Illustration 1 shows that the two-way valve is in the SAE position.

The patterns on the left side of the illustration show the possible configurations for the left control lever. The patterns on the right side of the illustration show the possible configurations for the right control lever.
|
Stick Out (1) - Move the control lever to this position in order to move the stick outward. |
|
Swing Right (2) - Move the control lever to this position in order to swing the upper structure to the right. |
|
Stick In (3) - Move the control lever to this position in order to move the stick inward. |
|
Swing Left (4) - Move the control lever to this position in order to swing the upper structure to the left. |
|
Boom Lower (5) - Move the control lever to this position in order to lower the boom. |
|
Bucket Dump (6) - Move the control lever to this position in order to dump the bucket. |
|
Boom Raise (7) - Move the control lever to this position in order to raise the boom. |
|
Bucket Close (8) - Move the control lever to this position in order to close the bucket. |
HOLD (9) - When the control lever is released from any position, the control lever will return to the HOLD position. Movement of the upper structure will stop.
Two functions may be performed at the same time by moving a control lever diagonally.
If the machine is equipped with a hydraulic hammer, the function of position (6) and of position (8) is different.
Hydraulic Hammer Raise (6) - Move the control lever to this position in order to raise the hydraulic hammer.
Hydraulic Hammer Lower (8) - Move the control lever to this position in order to lower the hydraulic hammer.
